Software Design Of DSO Human-machine Interation Based On Qt

The oscilloscope is necessary for any electrionic design work, with decades of development it has worked out kinds of high performance specs and more and more friendly human-oscilloscope interaction system. People are caring more about the feeling of using products as the informantion age coming, and they have higher expection of the human-oscilloscope interaction system when they choosing oscilloscope products than before. This project is aim to develop a friendly interaction system for oscilloscope with understanding the needs and rules based on Qt. the system is centered by the human-oscilloscope interface and has a self-defined font to support the interface’s view and has a design of communication interface to support its interaction with users. This project has several points below to study:1. Work out the design of human-oscilloscope interface. As the center of the system, this project has analysed the need of the interface, and design its structure and its menu. This interface has taken advantage of Qt in interface development and gives excellent experience to users.2. Work out the design of self-defined font base on Qt. in order to support the special view of oscilloscope and multi-lauguage view, this project developed a self-defined font with little size to save the space of the system. This font is designed by needs based on Qt and its file is created by software which is developed for the font specially.3. Work out the design of communication interface of oscilloscope. In this project, the interface needs to communicate with the keyboard and the network. A good interface is helpful for increasing the speed of communication. This project has designed the communication in two parts which are key-pressing communication and network communication.This project has constructed an interaction system for oscilloscope by a interface and a self-defined font and communication interfaces. The system gives users friendly experience and show the oscilloscope with accurate view and communication.
